Slot machines in online casinos

How do online casinos work? - people often wonder. How is the outcome of a spin on a slot machine or roulette wheel determined? Online casinos use a technology called random number generators (RNG). When you tap or click on the spin button of a slot game, numbers are generated and you win or lose according to the value of those numbers. Hence, it is not the casino that determines the outcome but a fair and random system. When you play at a licensed Portuguese online casino such as the ones you find on casino Portugal online, rest assured the games are audited regularly.

Why slots over table games, bingo, or sports betting?


The great thing about slot machines is that they are suitable for all demographics. Strategic card games such as poker or blackjack are mainly for men who like competition. Sports betting is favored by sports enthusiasts while bingo, keno, and lottery are mainly attractive to older women. Slots can be played by anyone—young adults or elderly people, women or men alike.
Popular slot games are attractive to all demographics. Titles such as Starburst, Gonzo’s Quest, and Mega Moolah are played by millions every day.


Slots are perfectly suitable for mobile play. Therefore, they can be enjoyed on the go - on the bus, on the lunch break at work, or on the family sofa. One game only lasts a few seconds so you won’t need time to concentrate and you can stop playing at any moment.

Variety of the games

There are thousands and thousands of slot games out there and new ones are created every day! It is impossible that you won’t find one that you like. They come in so many themes, such as popular culture, fantasy, history, mythology, sports, movies, and series. Accompanying music can completely transport players to another world and this is why these games are so immersive.

There are different variance levels with different slot games. Some people prefer to play with small money and don’t expect to win big, while others go for jackpot games where 6 or even 7 figures sums can be won.

Ease of use

The main advantage of slot games is that they are so easy to use. You won’t need to memorize the rules or have a strategy chart in front of you when you play. All you have to decide is how much money you want to wager on each spin. You cannot make a mistake in a slot game.

Free games

Almost any online casino offers slot games to be played in demo mode - without wagering any money. In land-based casinos, popular casino slot machines, of course, cannot be tried for free so playing online is a great way of getting familiar with a certain game. When you sign up with the best online casino, you will more often than not receive a welcome bonus that often comes as free spins. Apart from this, casinos regularly run promotions whereby you can receive more free spins as you deposit.

Engaging gameplay

Slot games, just like video games are very engaging and rewarding. When you play slot games - and especially low variance ones - you will get small wins on a regular basis. This is very rewarding and it keeps people engaged. Completing something is very satisfying and therefore it is hard to stop playing slots.


Slot machine games are the most popular types of casino games both in online and land-based casinos. The convenience, ease of use, and availability of free games make them attractive to novice players while the variety makes them suitable for all demographics.
